POST-DRVING APPARATUS.

l To all 'whom t may concern.' i l Be it known-that L'CoNsTANT liueinyny LAMorsn, subjectof the King of Great Britain, residing at Namur,` Labelle county, Province of Quebec, Canada, haveinvented certainfnew and useful Improvements in Post-.Driving Apparatus, and do hereby- Ydeclare that the following isa full, clear,...

and exact description of the invention, such as will enable others skilled in thegart to ywhich it appertainstomake and use the same.

The present invention relates to new and useful improvementsin post driving, apparatus.l

. The primary'object of the invention istlie jprovision of -a post driving apparatus in which the body portion or platform thereof may be maintained in a horizontal position, no matter how uneven the ground upon which the same is operating, may be.

i Another object of lthe invention y,is the provision ofmeans for adjusting the said platform laterally with respectgto its wheeled frame, and` also for adjusting'the post driving means longitudinally Vthe frame.

Still another object of the invention 1s the i provision of means for tilting the platform,

laterally relative t0y its vwheeled supporting frame, and retaining the said platformA in such'tilted position, to prevent any unde- Y sired movement. Y

Afurther object of the invention, isthe provision of means controlledby an operating crank, for tilting the post driving means,`which is pivotally connectedto the platform llongitudinally relative to said Y platform and wheeled supporting frame, for

.irregularityA of the ground.

adjustingthe apparatus with respect to the A further Object of the invention, is the provision of means, for simultaneously raising one side of the platform or body ofthe device and lowering the other, to conform to the unevenness ofY the ground.

A still further lobject of the invention is theprovision of a kpost driving apparatus,

which will be con'lparativelyY simpleand inexpensive to manufacture, reliableand efficient in use, and readily operated. t

With the above and other objects in view, the present invention resides `in the novelfeatures of construction, formation, combination, and arrangement of parts, to 'be l specification ofreaersratent. VPatelfyd Appncatin mea January 27, 1921. serial 110.440,41. l' i shafts 17 and 18:

Fing. 4, isan,endview'lthereofjl I y F 1g. 5 is a detail' sectional view, throughf one .of the adjusting pulleys; and, i Y c, Fig: 6 1s a plan View, of the journal for the sa1dpulley.f. j Y Referring no w-to theaccompanying drawings, bycorresponding characters of refermeral 1Q designates in general myfimproved apparatus which yconsists of ,a 'wheeled frame, 11 including opposite lf-ront, and rear yholsters 12 and 13,` of 'triangular formation and; to the apeXes of which are Apivotally mounted as at 14, a baseorplatform 15. l

A motor shown at 16 is mounted ajt-{therear end of the platform` 15, while intermediate the ends thereof is a transverse frame 16,'in

jbetweeen the upper end of the bar-26. Thisv cable passes overa pulley 30 secured tothe forward end of the platform 15,'and isattached at its opposite end toa drum 31 which is loosely mounted upon the shaft-19 but is adapted to be' driven therebyZby the clutch element 132, which isope'rated by. a hand lever 33. l Normally the drum 31 is looselyl mounted upon` the shaft-19 so that the-,operation of the pulley 22 has no effect. upon the same.- By operating the lever y33 the clutch 32 may ybe thrown into engagement with the -drum 31 andthe same rotated to raise the "weight 27' to the upper end ofthel .POSt driving dev1ce25, at which point, itmay be y L yence throughout theseveraly views the Ynuy theV upper and lower released by means of the clutch 32 through the medium of the hand lever 33 and will fall, striking the post, driving it into the ground. i

1n order to provide for the movement of the post driving mechanism 25 in its verti -cal relations to the platform 15 to agree withl the unevenness of the ground, a pair of rods 34y are threaded in the block 35 which are attached to the opposite side bars 26. y

The opposite ends of these rods 34 are provided with pinions 36 which mesh with corresponding pinions 37 keyed to the before mentioned shaft 17 and obviously upon the rotation of the crank 20 in opposite direction, the upper ends of the bars 26 will be moved outwardly or inwardly as desired,

so that the'device 25 will be at all timesk upwardly through these bearings through they sprocket wheels above referred to. Vertical 'counter shafts 47 are mounted on the frame 16 'and carry gears 48 at their upper ends which mesh with the gears 49 keyed to the before vdescribed shaft 18. Obviously upon the rotation of the cranks 21 the shafts 47 vwill be'rotated.

ySprocket wheels 50 are keyed to the lower end of the shafts 47 and over the same pass chains 51 and 52 which engage the before described sprocket .wheels 42 and 43 and upon therotation of the shaft, drive these sprocketk wheels in such manner, that the' body will be tilted either to the right or to the' left as desired to agree to the unevenness of the ground.

^ From the foregoing it will be readily seen that the latenal adjustment of the platform 15 together with the longitudinal adp justment of the driving mechanism 25, relative to the platform, will be such that the said driving mechanism will be at all times maintained in a vertical position for properly driving the posts in the ground.

The frame 10 may be provided with suitable wheels 53 by means of which the device can be transported from one locality to another'as desired.

g 'From the foregoing description taken in connection with the accompanying drawings it will be manifest that a fence post driving apparatus, is provided which will fulfil all of the necessary requirements of sucha device, and it should be understood in this connection, that various minor changes in the specific details of construction can be resorted to within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new and desire to sek lcure by Letters Patent is 1. A machine of the character described including a wheeled frame, bolsters at the end of said wheeled frame, a platform pivoted at its ends to the upper ends of said bolsters for tilting movement thereon, threaded rods secured to the bolsters, guides carried by the oppositev sides of the platform for receiving said rods, said guides having openings with curved surfaces formed therein, sprockets threaded upon the said rods, eX- tensions on the sprockets and fitting in the said openings, means for rotating said sprockets in opposite directions upon opposite sides of the frame, and tilting the platform laterally relative to the frame, va driving apparatus mounted upon said frame, and meansfor tilting the driving apparatus longitudinally relative to the frame. 2. A machine of the character described including a frame, a platform mounted at its ends upon said frame to tilt laterally thereof, threaded rods carried by the frame and passing through the guides secured to the platform, sprockets threaded upon said rods, extensions on the sprockets and fitted in openings formed said guides, means for rotating the sprockets upon opposite sides of the frame, in opposite directions simultaneously and tilting the platform in opposite directions relative to the frame, a driving apparatus pivoted to one end of the frame, threaded rods passing through said apparatus and means for rotating said threaded rods, and tilting the driving apparatus relative to the frame.

3. A machine of the character described including a tilting platform, a plurality of shafts located upon saidV platform, means for rotating said shafts, means operatively connected with said shafts to tilt said platform in one direction, a driving apparatus mounted upon said platform, a means for tilting the driving apparatus in an opposite direction to the platform, whereby said driving apparatus will at all times be maintained in a vertical position.

4. A device of the character described including a tilting platform, a frame mounted thereon, shafts mounted in said frame, threaded rods passing through the ends of said platform, sprockets threaded upon said rods, and engaging the guides in which the rods are mounted, means operatively connecting the sprockets and one of theshafts for rotating the sprockets upon opposite sides' of the framein opposite directions and' tilting the platforms in one direction,
